Brand owners frustrated with introducing unique new products or engaged in differentiating products packaged in trays and pouches should strongly consider running tests on an Allpax 2402 multimode R&D retort. --Adam Reichert, Thermal Processing Engineer

Allpax, powered by Pro Mach, will feature at Pack Expo 2014 in Chicago the results of taste and appearance tests conducted on a range of low-acid foods made shelf stable in high-and low-speed reciprocating retorts. (Allpax Pack Expo Booth # N-5317)

Allpax found that Shaka® high-speed reciprocating retorts are ideal for processing hard to retort foods and producing shelf-stable premium foods, abilities which can help companies achieve product differentiation. Gentle Motion lower-speed reciprocating retorts are optimal for increasing retort room throughput and quality. Research results, including comparative photos, tasting notes, and processing times, will be showcased at the Allpax Pack Expo booth along with a Shaka retort.

Compared to static retorts, reciprocating retorts such as Shaka and Gentle Motion distribute heat faster and more evenly in pouches and semi-rigid plastic trays that are oriented horizontally in a retort basket.

Shaka Test Results

A shrimp pasta and tomato cream sauce dish processed in a Shaka retort produced shrimp with an outstanding stove top texture. The flavor and appearance were excellent. A pasta and cheese dish was also judged superior when processed in a Shaka retort. A béchamel white sauce and guacamole dip, notoriously difficult low-acid foods to sterilize, also showed exceptional results. Allpax found during its testing that Shaka is ideal for producing purees. A split pea and ham dish packaged in a pouch had, like the shrimp dish, superior taste and appearance.

“Brand owners frustrated with the introduction of unique new products or engaged in efforts to differentiate products packaged in trays and pouches should strongly consider running tests on an Allpax 2402 multimode R&D retort which has Shaka and Gentle Motion capabilities or having Allpax run tests in our facility,” said Adam Reichert, Thermal Processing Technician/Process Engineer at Allpax. “The results may be quite encouraging.”

Gentle Motion Sterilization Increases Throughput and Retort Room Capacity

Gentle Motion decreased sterilization time by 20 to 60 percent on the six foods tested. In every case the taste, texture, and appearance were equal or superior to dishes processed in a static retort. Shorter sterilization time made dishes look fresh, more natural, and less processed. “Beef stew, for example, processed in 48 minutes compared to the static retort’s 82 minutes and demonstrated comparable taste and texture,” Reichert said.

Pack Expo attendees will have access to complete test results. For more information on R&D options for Shaka and Gentle Motion, call 1-888-893-9277 and visit
